Change logging for node numbers. Add new Log::Write method that takes a

node number as an argument. All formatting is now done in the log object
instead of being scattered around. Also added a new helper routine that
takes a Msg object and returns the target node id. In the case of no
message it returns 0 and no node number will be output in the log. See
Driver::GetNodeNumber.
Not all the classes use the new Log::Write yet.
Retreive SUC node id. Just uncomment existing code.
Add error checking to pthreads mutex calls.
Don't do the Query_Wakeup phase for FLiRS nodes as they don't seem to
respond to wakeup class messages and they will respond to others.
Add missing LockNodes/ReleaseNodes around node array scan when removing
controller that returns 0 for node number.
